DisplayLink has worked for many months to maintain support for its users during the transition from macOS High Sierra to Mojave. While functionality such as Ethernet and audio or charging, where implemented, is unaffected on all releases, display connectivity has been limited on macOS releases from 10.13.4 through 10.13.6.

Developers/users with access to Apple’s fifth developer preview of 10.14 Mojave, released on 30th July, will see full support has now been restored for multiple extended DisplayLink displays where DisplayLink driver v4.3 beta 5 (http://www.displaylink.com/downloads/file?d=175) is installed. We are doing wide scale testing of v4.3 beta against this preview and will release a new driver upon general availability of 10.14.

Installing macOS 10.13.4, or newer, will cause DisplayLink connected displays to go blank after the OS update when using DisplayLink driver v4.1. Extended displays continue to work as expected in macOS 10.13.3 and below.
Functionality such as Ethernet and audio, where implemented, is unaffected.

The third developer preview of 10.14 has changed behaviour. Displays using DisplayLink technology will be present in System Preferences – Display. The displays can be activated, and the mouse is visible, but otherwise the displays are black. Should you have already installed that OS version, simply use DisplayLink driver v4.3 beta 6 (http://www.displaylink.com/downloads/file?d=180) to force the AirPlay interim whilst the work continues.
We do not recommend using that OS version for extended desktop changes as it brings no benefit compared to previous versions.
When a new version brings value, we will obviously notify you.

Our team continues to progress towards a solution which would both restore full extended display support for multiple DisplayLink displays in a future release of macOS and defend that functionality in the future. As daily users of the technology ourselves, we truly understand how disruptive this loss of functionality affecting the full ecosystem can be. Despite getting closer to tell more about roll out, we stay unable to provide a time-frame or a date for release of this solution.
We will keep providing updates to this message.

Thank you for your extended patience. We appreciate your feedback and support.

DisplayLink driver v4.3 beta 5 currently provides an interim solution with one extended USB display (720p or 1080p) on macOS 10.13.4, 10.13.5 and 10.14 first developer previews, using Apple AirPlay® on machines with that feature. All additional DisplayLink screens will be cloning the primary display.

Installing macOS 10.13.4 will cause DisplayLink connected displays to go blank after the OS update when using DisplayLink driver v4.1. Extended displays continue to work as expected in macOS 10.13.3, and we can only recommend that you stay on macOS 10.13.3 or earlier if you require this feature and have not already updated. Functionality such as Ethernet and audio, where implemented, is unaffected.

Today, we released DisplayLink driver v4.3 beta 5 providing an interim solution with one extended USB display (720p or 1080p) on macOS 10.13.4, using Apple AirPlay®. All additional DisplayLink screens will be cloning the primary display.
DisplayLink driver v4.3 beta5 fixes the update mechanism, so you don’t have to uninstall the previous version before installing the new one. You no longer need to re-plug your USB device after rebooting, and, with the accessibility permission, AirPlay display will also automatically be reactivated when docking and after rebooting. I preferred delaying this message to postponing the delivery of these usability improvements you asked for.http://www.displaylink.com/downloads/file?d=175 for 4.3 Beta 5.

We are aware that installing macOS version 10.13.4 will cause DisplayLink connected displays to go blank after the OS upgrade, with the latest DisplayLink driver release 4.1 installed. Extended displays continue to work as expected in macOS 10.13.3, and we recommend that you stay on macOS 10.13.3 or earlier if you require this feature, and have not already upgraded. Functionality such as Ethernet and audio, where implemented, is unaffected.

Our team has made some solid progress towards finding a solution which would restore extended display support for multiple DisplayLink displays, in a future release of macOS, but we are unable to provide a timeframe or a date for release of this solution at this time.

Meanwhile, we have an interim solution which enables one extended USB display (up to 1080p) on macOS 10.13.4, using AirPlay®. Additional DisplayLink screens will be in cloned mode. DisplayLink driver v4.3 beta 3 is available to download from our website today – http://www.displaylink.com/downloads/file?d=167

We are aware that installing macOS version 10.13.4 will cause DisplayLink connected displays to go blank after the OS upgrade, with the latest DisplayLink driver release 4.1 installed.

Our team has made some solid progress towards finding a solution which would restore extended display support in a future release of macOS. We are still unable to provide a timeframe or a date for release of this solution.
Meanwhile, we have been developing a partial workaround solution which would add one extended USB display (up to 1080p) on macOS 10.13.4. We are aiming to release a preview version of this driver in around 7 to 10 days. The precise date depends on how the solution performs under deeper and wider testing, and how long it takes to resolve remaining issues. We expect the driver to enable one extended 1080p screen, and one cloned screen connected to a DisplayLink device. There may be some other functional limitations.
The new alpha driver will be posted online as soon as possible.

As previously advised to users, we are aware that installing macOS version 10.13.4 will cause DisplayLink connected displays to go blank after the OS update, with the latest DisplayLink driver release 4.1 installed.

Extended displays continue to work as expected in macOS 10.13.3 – this is why we recommend remaining on macOS 10.13.3 or earlier at this time. Functionality such as Ethernet and audio, where implemented, is unaffected on macOS update.

DisplayLink has committed significant resources to finding a way to restore extended mode display support in a future release of macOS.
We have made solid progress towards identifying a solution, however our team needs to complete more work before we can communicate a release plan for a driver that will restore extended mode displays.

Installing macOS release 10.13.4 will cause DisplayLink connected displays to go blank after the OS upgrade when using our driver v4.1. (Functionality such as Ethernet and/or audio, where implemented, is unaffected.) Extended display support continues to work as expected in mac OS 10.13.3 and that is why we recommend you stay on 10.13.3 for now, if you have not already upgraded.

For users that have already upgraded to 10.13.4, we have released 4.3 Beta 2, which enables cloning of the native display on DisplayLink connected screens. We do not regard this as a long-term solution and will continue to pursue any paths to restore extended display support on macOS. The 4.3 Beta 2 release can be downloaded from http://www.displaylink.com/downloads/file?id=1131.

As we use our own technology every day, we truly understand that this loss of functionality on the OS upgrade is very frustrating. We are continuing to explore with Apple routes to a solution. In the meantime, our teams are working hard analysing potential workarounds, which could enable some level of extended desktop functionality in 10.13.4. Finding a solution to this issue continues to have the highest priority within DisplayLink, and we are providing any support we can to our mac teams.

Unfortunately, we are not yet able to give a date for delivering a solution but we will continue to update you on this thread as soon as we have further information to share. You can also use the contact form to create a ticket with your email address and ask to be added to an email list dedicated to this issue.

Finding a solution to this issue remains the highest business priority within DisplayLink.
Our teams are investigating several potential workarounds that could enable some level of extended desktop functionality to be restored in 10.13.4. In parallel, we are continuing to explore with Apple routes to a permanent and complete solution.

In the meantime, we have today released a second beta of our 4.3 driver. Installing this driver will enable cloning of the native display on DisplayLink connected screens. 4.3 Beta 2 improves the current workaround by preserving the primary display aspect ratio and allowing to select which screen is cloned in a multiple display setup. Our v4.3 driver can be downloaded from http://www.displaylink.com/downloads/file?id=1131.
We do not regard this as a long term solution and will continue to work hard on finding a path to restore extended display support on macOS.

Unfortunately, at this stage, we are unable to give a dates for either a workaround or a complete solution. We will, however, update you on this thread as soon as we have further information to share. If you have left your email address accessible to us with your feedback (ticket, forum, suggestion), this email address will be added to a list dedicated to this issue.

We are aware that installing macOS release Version 10.13.4 will cause DisplayLink connected displays to go blank after the OS upgrade, with the current DisplayLink driver [4.1] installed. Functionality such as Ethernet and audio, where implemented, is unaffected. We have alerted Apple to this issue and are working hard to find a resolution. These features continue to work as expected in 10.13.3.

In the meantime, we are releasing a new driver [4.3] that will enable clone mode, but not mirror or extended mode displays in 10.13.4. If you require mirror or extended mode displays, we recommend that you stay on macOS 10.13.3 at this time.

We understand that this loss of functionality on OS upgrade is potentially disruptive for our users and customers. Please be assured that this issue has the highest business priority in DisplayLink. We thank you for your patience and will provide an update on this situation, as soon as we have further information to share.

Hello, if you have DisplayLink 4.3 beta 5 with Mojave Preview 4 (Beta 5) and are experiencing black external displays with only the mouse cursor even after reinstalling the driver, please create a ticket with your logs as described in https://support.displaylink.com/knowledgebase/articles/755301. We don't have the reproduction internally to analyse yet so logs are necessary to give hints on what could be going wrong.

And for those noticing that they can only mirror and the resolution is not adapting to the new screen: we've noticed that AirPlay is interrupting DisplayLink's workaround. If you turn wi-fi off before you plug in, the DisplayLink driver will connect properly; you can then use the AirPlay menu in the notifications area near the clock to use it as an extended screen. (You can turn wi-fi on afterwards.)
Make sure that a) the DisplayLink driver has been authorised as a system extension in the Security and Privacy system preferences screen, and that the DisplayLinkUserAgent has been approved in the Privacy > Accessibility tab of the same screen.

For all of you on 10.13.6 who are having problems with the v4.3 beta 5 not working with airplay, I followed the tip from Anonymous 7/31 @10:27 and went into system preferences/security/general and checked for software blocked from loading. Sure enough DisplayLink was listed there and as soon as I unblocked it and did a restart the USB display showed up in airplay and worked perfectly. I'm on a late 2012 MacMini I7 2.6 quad core.

Macbook Air, 10.13.6. Ran through all of the steps to install the driver and it's a blank screen. It's being detected by the monitor, but no option to select the monitor from the airplay dropdown so the monitor remains dark. Any ideas?

@RJR I've noticed the solution got unstable on 10.13.6. Sometimes it simply won't airplay to DisplayLink. I usually see this happen when I leave the system locked and the screen goes to stand-by for a while. Then I have to turn the dock station off and on (sometimes multiple times) to get it back to work.

4.3 beta with Mojave Preview 4 (Beta 5) works perfectly for me using two different DisplayLink docking stations on my 2012 MacBook Pro 13. Apple finally saw this as a bug, and while they won't fix it in High Sierra, I wouldn't hesitate to use Mojave at this point, as it is stable.

I am using macOS 10.13.6 and v4.3 beta 5 and a Dual-4K Docking Station from StarTech.com (DK30A2DH). I get on startup the message "DisplayLink Graphics Driver is running in clone mode". Both displays show the cloned built-in display, but I don't get the option to use them as separate displays. Nothing happens when I click on "AirPlay link to: DisplayLink" as described in the FAQ. If I connect the device after the login as described in the FAQ I still get the message, but there is no DisplayLink to select for AirPlay.

Mojave developpers beta 5 here (18A347e), and still getting blank screen with the cursor. The kernel extension consent is disabled, so it's not the issue, and this is a fresh macOS install. (`spctl kext-consent disable` in recovery). Since everything is working for some user, this is not an Apple issue anymore, but definitely a bug in the drivers. Fix your crap, and track the bugs/resolution correctly: it's getting ridiculous.

MacBook Pro w. TB 13" 2018, Mojave beta 4 (public) and 4.3.0.5:
2 extended Displays are back, but one is not recognized correctly, the resolution can not be adjusted.
Tested with different screens and cables.

10.14 Mojave public beta 4 (released today) is the same as the fifth developper preview. It's working perfectly on my macbook air 11" mid-2012 with DisplayLink driver v4.3 beta 5.

It's been a long ride without my 3rd monitor, especially as my 11" macbook doesn't provide me with much space to work on.

I recommend you go to https://beta.apple.com/sp/betaprogram/ and download the latest public beta of Mojave. It's free and you don't need to be a developer. It's running perfectly smooth on my Mac and the new dark mode alone is worth upgrading.
